4、insert_memory_breakpoint,首先调用read_inferior_memory读取插入断点的地址,然后调用bp_opcode获取断点指令的执行地址,再然后调用bp_size获取断点指令的长度,实现将断点指令插入到想要执行断点动作的地址。 GDB底层实现原理小结: 一个简单的ptrace体验,跑起来体验一下流程 ...
$ gdb core_dump core 提示出错位置。 ⑷Core Dump的核心转储文件目录和命名规则 系统默认corefile是生成在程序的执行目录下或者程序启动调用了chdir之后的目录,我们可以通过设置生成corefile的格式来控制它,让其生成在固定的目录下(对应的是自己的目录,不要直接写我的目录),并让每次启动后自动生效。 (1)在/etc/...
